Description
Technical field
This utility model relates to the instrument cutting valuable gem-jade, is specifically related to a kind of inner diamond slicing blade.
Background technology
Inner diamond slicing blade is the one in diamond tool, is mainly used in processing precious materials, as artificial brilliant
The cutting of the material stiff materials such as body, natural gemstone, valuable pottery, have joint-cutting little, cutting flatness is good, grinding efficiency is high
Advantage.
The manufacture method of existing inner diamond slicing blade is to be opened by the face at inner circle edge of a knife place on stainless steel base
Begin to extend direct combination nickel diamond in the range of 2.0-3.0mm towards matrix outer circumference surface.The Buddha's warrior attendant that this method makes
In stone, circular knife is simple due to processing technology, can accomplish scale production and be widely used.But diamond prepared by the method
Inner circle cutting blade can not increase thickness of coating, due to coating due to the thickness of the edge of a knife to be ensured within 0.24-0.40mm
The restriction of thickness makes the diamond number of plies in coating few, in use causes diamond coating to be stripped the most completely,
And the edge of a knife can be gone out without sword, thus cause service life of existing inner diamond slicing blade shorter.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of thickness of knife edge is little but diamond coating thickness big and plating
The inner diamond slicing blade that in Ceng, the diamond number of plies is many.
Inner diamond slicing blade described in the utility model, including circular base, wherein:
Described circular base include the first first type surface and relative the second first type surface of the first first type surface, the 3rd first type surface and
The 4th first type surface that 3rd first type surface is relative, and be positioned at the first side surface of outer circumferential edges and be positioned at the of inner circumferential edge
Two side surfaces；
Described 3rd first type surface and the 4th first type surface be respectively from the upper/lower terminal of described second side surface respectively outward towards
First side face directions extends certain distance and is formed, and described 3rd first type surface is at circular base width radially and the 4th master meter
Face is equal at circular base width radially；
Described 3rd first type surface and the first first type surface are connected by first annular side, described 4th first type surface and the second master
Surface is connected by the second annular side, described first annular side circular base axially on height and the second annular side
Height on circular base is axial is equal；
3rd first type surface, the 4th first type surface and the second side surface are provided with the diamond containing diamond particles
Coating.
In technique scheme, the top end face of the diamond coating on described 3rd first type surface should be higher than that the first first type surface,
The bottom face of the diamond coating on the 4th first type surface should exceed the second first type surface, is the most just conducive to cutting operation；Generally feelings
Under condition, the top end face preferably controlling the diamond coating on the 3rd first type surface exceeds the first first type surface 0.02-0.05mm, and the 4th is main
The bottom face of the diamond coating on surface exceeds the second first type surface 0.02-0.03mm, such exceed distance and not only contributes to
Cutting operation, the effect also acting as reduction cutting seam is conducive to the eliminating of the swarf in cutting process simultaneously.
Inner circle cutting blade described in the utility model is owing to first offering less than matrix on the second side surface of circular base
3rd first type surface of core and the 4th first type surface, make diamond particles can be partially accommodated in the 3rd first type surface and the first master
In the space that surface and the 4th first type surface and the second first type surface are formed, thus effectively reduce in prior art because directly justifying
The cutting sheet thickness of knife edge that shape matrix surface consolidated diamond granule is formed, and then joint-cutting can be reduced, reduce processed work
The waste of part.On the other hand, on the premise of controlling identical thickness of knife edge, owing to diamond particles can be partially accommodated in the
In the space that three first type surfaces and the first first type surface and the 4th first type surface and the second first type surface are formed, be equivalent to increase diamond
The space that granule can occupy, i.e. adds the arrangement number of plies of diamond particles, in use can have the gold of more layers
Hard rock granule is worn, and is effectively improved the service life of inner diamond slicing blade.
In order to obtain ultra-thin cutting slice, the circular base that thickness is less can be selected, in the process of the test of the applicant
Finding, when the thickness of circular base is 0.10-0.15mm, the spacing of the 3rd first type surface and the 4th first type surface is 0.04-
0.06mm is more suitable, now, the part constituted using the 3rd first type surface, the 4th first type surface and the second side surface as supporter,
In use when the diamond on the edge of a knife flake off into supporter occur time, owing to supporter is the thinnest, meeting and coating Buddha's warrior attendant
Stone coating is equally worn, and is equal to add the coating diamond number of plies in the cutting direction, extends blade further
Service life.
The thickness of the circular base mentioned in the application, refers between the first first type surface of circular base and the second first type surface
Away from.
The inner diamond slicing blade that above-mentioned preparation method prepares needs to carry out edge of a knife correction before the use, concrete
Modification method is identical with existing conventional techniques.
Compared with prior art, feature of the present utility model is:
1, on the second side surface of circular base, the 3rd first type surface less than matrix core and the 4th master are first offered
Surface, makes diamond particles can be partially accommodated in the 3rd first type surface and the first first type surface and the 4th first type surface and the second first type surface
In the space formed, thus effectively reduce in prior art because of directly in circular base surface consolidated diamond granule institute shape
The cutting sheet thickness of knife edge become, and then joint-cutting can be reduced, reduce the waste of workpiece to be machined.On the other hand, identical in control
Thickness of knife edge on the premise of, owing to diamond particles can be partially accommodated in the 3rd first type surface and the first first type surface and the 4th main
In the space that surface and the second first type surface are formed, be equivalent to increase the space that diamond particles can occupy, i.e. add
The arrangement number of plies of diamond particles, in use can have the diamond particles of more layers to be worn, be effectively improved Buddha's warrior attendant
The service life of stone inner circle cutting blade.
2, further, it is the circular base of 0.10-0.15mm when selecting thickness, and controls the 3rd first type surface and the 4th master
The inner diamond slicing blade prepared when the spacing on surface is 0.03-0.06mm, with the 3rd first type surface, the 4th first type surface and the
Two side surfaces constitute part as supporter, in use when the diamond on the edge of a knife flake off into supporter occur time,
Owing to supporter is the thinnest, meeting the same is worn with the diamond coating of coating, is equal to add coating in the cutting direction
The diamond number of plies, extends the service life of blade further；Meanwhile, after supporter is worn, coating backbone is exposed immediately
Hard and sharp diamond particles, thus reach inner diamond slicing blade and go out sword and ultra-thin purpose continuously.
